Not the tweak I would make, but it does retain the original sentiment, and this is an evolving wiki document, after all.
As I mentioned to Bouncl, who PM'd me about this, I do want to point out that the scientist being quoted regarding vellum is theorizing. It's a hypothesis restricted to that particular scientist. He may not be right. Vellum works, this is why he thinks it works, but he could just as easily be totally wrong. Vellum is just an interesting substance—one of the oldest things we inscribe writing on, so I thought it would be interesting to include it. The "high-tech" version could certainly be added in as an alternate hypothesis or even an experiment log. I think that it would represent a logical progression in attempts at new containment procedures.
I'd also like to mention that the Memo, while interesting, cites the SCP as a "nonexistent" number. I've never been comfortable with that characterization. The problem with this phenomenon is that it is very existent, though contained. Still, this is a community, and the addition was made with good intent and a desire to improve the piece. I'm happy the entry is interesting enough for people to want to discuss it and make contributions.
